One way of fulfilling these contradicting requirements is lightweight material construction, in which a reduction in body weight can be achieved through the substitution of steel by modern lightweight construction materials.
(a) Part formed considering 45o Wall Angle (b) Part formed Considering 60o Wall Angle Fig. 3: Comparison of SPIF Numerical Results Before and After Spring-back After completing the forming process, the last step stored data such as stress, strain, and thickness was used to model the implicit spring-back simulation for evaluating the presence of a geometric change in the formed part.

To calculate activation yield, it is the percentage of mass of AC after carbonization process.The surface area of samples was obtained by application of Belsorp Adsorption/Desorption data analysis software with the instrument.
The adsorbent pH may influence the efficiency in pH reduction.

The average roughness and RMS roughness of all films were calculated by extracted data from AFM images and shown in Fig. 6.
However, the reduction of the average roughness and RMS roughness at 6s and 10s may be attributed to the ravine-like surface that turned to nearly equable surface again.

Measuring results of illuminance [lx]   Measuring time 9:30~10:00 12:40~13:10 15:50~16:20 Solar Light Pipe 1 Sunny Cloudy Overcast 177.8 134.2 70 253.1 225.3 90.9 134.8 90.7 59 Solar Light Pipe 2 Sunny Cloudy Overcast 145.3 104.5 58 203.4 187.1 78 105.6 65.8 45.6 Obviously, the internal illuminance is the lowest when the weather is overcast, and the results of that day can be chosen as a reference data.
It comes to the conclusion that the internal and external illuminance present similar change rule, and getting lower with the reduction of the solar altitude angles.

However, a further lowering of the off-cut angle can be advantageous under the economic point of view, leading to a significant reduction of the waste material during boule cutting process.
Evidently, the data follow a single slope line, indicating the presence an intrinsic mechanism of the oxide breakdown.

Experience of SV exploitation shows that as far as the increase in a necessary term of active functioning, besides the factors of depreciation of operation and exploitation, substantially increases importance as more as possible exact consideration of long-term influence of the factors of space environment on the object and development of effective, in every respect, procedures for this influence reduction.
A purpose of the tests is an operating time of initial data for the prognosis of expected intensity of single events of a semiconductor device at a regular mode of operation in natural conditions.

ZrC can be prepared by several techniques, which include reaction between elemental powders, carbothermal reduction of metal-oxide or sol-gel process [5].
With the increase of compacting pressure, the productive rate of ZrC increases from 68.88 to 75.56% based on XRD data, while the weight loss decreases from 8.67 to 7.67%.

These damages are very dangerous because they cannot be detected visually and promote important reductions of the compressive and flexural residual strength [1-3].
The method requires the local strengths (σu,i, i= I, II, III) and the critical strain energies release rates (Gic) as inputted data parameters.
